Apex 4.1.1 and 4.2.1http://www.orafaq.com/forum/./mv/msg/185367/572781/#msg_572781
"... I believe there are fundamental differences between 4.1 and 4.2, in that changes need to be made to an app developed under 4.1 to run under 4.2... so they won't be able to just export an app from DEV and import into PROD and be sure it will work... "

I've no problem doing this, but is that reasoning actually correct? Is upgrading a hassle, and staying on the release a sensible thing to do?

Thank you for any insight.]]>John Watson2012-12-17T16:25:54-00:00Re: Apex 4.1.1 and 4.2.1http://www.orafaq.com/forum/./mv/msg/185367/572807/#msg_572807
As far as I can tell (based on my previous experience):

if you export an application from a lower version and import it into a higher version, it will most probably work OK

if you export an application from a higher version and import it into a lower version, it won't work at all

I doubt that there are fundamental differences between these two versions; didn't test it (yet) - we installed 4.2 last Friday but I didn't have time to do export/import & test.]]>Littlefoot2012-12-17T21:26:25-00:00Re: Apex 4.1.1 and 4.2.1http://www.orafaq.com/forum/./mv/msg/185367/572853/#msg_572853

LF, this is a new app and we are building the machine that will be used in producton, so the situation is a bit different from the usual dev/prod set up for a running app. I think the project manager is concerned that upgrading now would entail a lot of work and delay the project's live date. If you do try to transfer one of your applications to 4.2.1, I would be interested to know if goes smoothly.
CS - if the upgrades were straightforward for you, perhaps it will be for everyone. Thank you for the information, I'll pass it on.
